Retroperitoneal exposure of the abdominal aorta is usually performed through a left flank incision. An alternative approach to the abdominal aorta is described utilizing a right flank incision. Indications for the use of the right retroperitoneal approach during surgery for aortic aneurysms include right renal artery stenosis, right iliac artery aneurysm, need for simultaneous cholecystectomy, multiple or recent intraabdominal procedures, and sigmoid colostomy. A series of 17 patients is presented to illustrate the utility of this approach. There was one operative death in an emergent patient; the cause of death was not related to the method of aortic exposure. The remaining patients recovered quickly. The anatomic advantages and limitations of this exposure are discussed. We believe that retroperitoneal aortic exposure is superior to midline transperitoneal exposure. Aortic exposure utilizing a right retroperitoneal approach is a useful option in the surgical armamentarium.
